Description

Technical Field

[0001] This utility model relates to the field of automotive seat crossbeam technology, specifically to an automotive seat crossbeam assembly. Background Technology

[0002] During the car assembly process, car seats need to be installed inside the car. This process requires first installing the crossbeam assembly in the car, and then fixing the crossbeam assemblies together with welded nuts to enhance the connection rigidity between them. This ensures the strength and durability of the car seat mounting points. In the event of a collision or other external forces, the seat crossbeam assembly can effectively transfer forces and torques to the vehicle body structure, playing a role in dispersing and buffering forces, and reducing injury to passengers.

[0003] When the crossbeam assembly is installed between the car seat and the seat, the connection point is in a smooth state, meaning the flat surface of the crossbeam assembly is directly connected to the flat surface of the car seat. When the car brakes suddenly, the connection point between the crossbeam assembly and the car seat will be subjected to a certain impact. At this time, the rigid connection without a buffer structure causes the seat to be impacted forward due to inertia, and the crossbeam assembly has to withstand huge instantaneous tensile or shear forces, which may lead to cracking at the connection point and affect the stability of the connection between the crossbeam assembly and the car seat. To address the shortcomings of the existing technology, we propose a new car seat crossbeam assembly to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an automotive seat crossbeam assembly. This solves the problem that when the flat surface of the crossbeam assembly is directly connected to the flat surface of the automotive seat, the connection point between the crossbeam assembly and the seat is subjected to impact during sudden braking or other events. The rigid connection without a buffer structure causes the seat to be thrown forward due to inertia, forcing the crossbeam assembly to withstand enormous instantaneous tensile or shear forces. This can lead to cracking at the connection point, affecting the stability of the connection between the crossbeam assembly and the automotive seat.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automotive seat crossbeam assembly, comprising a crossbeam body and a welding nut mounting platform fixedly disposed on the top surface of the crossbeam body for fixing the automotive seat to the crossbeam body. Reinforcing mechanisms are provided on both the upper and lower sides of the crossbeam body, and the reinforcing mechanisms include:

[0006] The first reinforcing toothed plate is fixedly installed on the bottom surface of the main body of the crossbeam;

[0007] The second reinforcing toothed plate is fixedly installed on the top surface of the main body of the crossbeam;

[0008] The honeycomb core is fixedly disposed on the inclined inner wall of the first reinforcing tooth plate and the second reinforcing tooth plate;

[0009] The positioning block is fixedly installed on the inner wall of the second reinforcing tooth plate, and the positioning block is used to connect and position the crossbeam body and the car seat.

[0010] Preferably, the serrations of the first reinforcing tooth plate and the second reinforcing tooth plate are perpendicular to each other.

[0011] Preferably, a damping layer is fixedly connected between the bottom surface of the second reinforcing tooth plate and the top surface of the crossbeam body.

[0012] Preferably, an extension seat is fixedly connected to the bottom surface of the main body of the crossbeam.

[0013] Preferably, a damping layer is fixedly connected between the bottom surface of the extension seat and the top surface of the first reinforcing tooth plate.

[0014] Preferably, a welding edge is fixedly connected to the side of the extension seat, and a first reinforcing tooth plate is fixedly connected to the bottom surface of the welding edge.

[0015] Preferably, the inner wall of the main body of the crossbeam is fixedly connected with multiple sets of reinforcing ribs.

[0016] Preferably, a flange is fixedly connected to the upper end of the outer wall of the main body of the crossbeam.

[0017] This utility model discloses an automotive seat crossbeam assembly, which has the following beneficial effects: The automotive seat crossbeam assembly, by setting a first reinforcing tooth plate and a second reinforcing tooth plate on the upper and lower sides of the crossbeam body, with the sawtooth directions of the first reinforcing tooth plate and the second reinforcing tooth plate being perpendicular, can increase the connection stiffness between the automotive seat, the crossbeam assembly and the vehicle from multiple directions. Furthermore, by superimposing structures such as damping layers, honeycomb cores, reinforcing ribs and positioning blocks, it can optimize the support strength of the crossbeam assembly, save the production cost of the crossbeam assembly and extend the service life of the crossbeam assembly, ensuring that the crossbeam assembly can provide stable support for the automotive seat.

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] This application provides an automotive seat crossbeam assembly that solves the problem of direct connection between the flat surface of the crossbeam assembly and the flat surface of the automotive seat. When the car brakes suddenly, the connection between the crossbeam assembly and the automotive seat will be subjected to a certain impact. At this time, the rigid connection without a buffer structure causes the seat to be impacted forward due to inertia, and the crossbeam assembly has to withstand huge instantaneous tensile or shear forces, which may lead to cracking at the connection point and affect the stability of the connection between the crossbeam assembly and the automotive seat. This application provides enhanced buffering and protection for the crossbeam assembly and the automotive seat in multiple directions.

[0027] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0028] This utility model discloses an automobile seat crossbeam assembly.

[0029] According to the appendix Figure 1-5As shown, the assembly includes a crossbeam body 1 and a welding nut mounting platform 11 fixedly mounted on the top surface of the crossbeam body 1 for fixing the car seat to the crossbeam body 1. The car seat is first threadedly connected to the welding nut mounting platform 11 via welding nuts to fix them together. A flange 3 is fixedly connected to the upper end of the outer wall of the crossbeam body 1. The flange 3 is fixedly connected to the inner wall of the car by welding. Multiple sets of reinforcing ribs 5 are fixedly connected to the inner wall of the crossbeam body 1. The crossbeam body 1 is inverted U-shaped. The reinforcing ribs 5 can effectively increase the structural rigidity and stability of the crossbeam assembly and prevent the crossbeam body 1 from undergoing severe deformation under external forces.

[0030] See attached document Figure 2-5 The main body of the crossbeam 1 is equipped with reinforcing mechanisms 4 on both its upper and lower sides. These reinforcing mechanisms 4 increase the stability of the connection between the main body of the crossbeam 1 and the car seat, and also enhance the stability of the connection between the main body of the crossbeam 1 and the car. The reinforcing mechanism 4 includes a first reinforcing toothed plate 41, which is fixedly mounted on the bottom surface of the main body of the crossbeam 1, and a second reinforcing toothed plate 42, which is fixedly mounted on the top surface of the main body of the crossbeam 1. The serrations of the first reinforcing toothed plate 41 and the second reinforcing toothed plate 42 are perpendicular to each other. Figure 3 From a perspective, the first reinforcing toothed plate 41 is horizontally aligned with the long side of the crossbeam body 1, and the second reinforcing toothed plate 42 is vertically aligned with the long side of the crossbeam body 1. Thus, under the action of the two sets of reinforcing toothed plates 41 and 42 with different tooth orientations, the connection and reinforcement of the device connected to the second reinforcing toothed plate 42 are strengthened from multiple directions. The minute deformation of the tooth tips at the first and second reinforcing toothed plates 41 and 42 can absorb local stress, preventing stress concentration on the bottom surface of the crossbeam body 1 due to rigid contact, such as crack initiation. The undulating structure of the teeth is equivalent to forming a micro-reinforcing element on the bottom surface of the crossbeam body 1, increasing the moment of inertia of the section. For example, the teeth of the second reinforcing toothed plate 42 cooperate with the groove of the seat base, and the first reinforcing toothed plate 41 cooperates with the surface of the car interior wall mounting bracket. The meshing of the teeth creates a mechanical engagement, increasing friction and suppressing the displacement of the crossbeam under dynamic loads, such as rapid acceleration, braking, and collisions. This increases the stability of the car seat inside the vehicle. In particular, the serrated structure rigidity of the first reinforcing tooth plate 41 and the second reinforcing tooth plate 42 allows for a reduction in the thickness of the base plate of the crossbeam body 1 within a certain range. This reduces the amount of material required for the production of the crossbeam assembly, effectively saving materials while maintaining the same mechanical properties. The first reinforcing tooth plate 41 and the second reinforcing tooth plate 42 can replace rubber anti-slip pads or anti-slip coatings, reducing the number of parts and assembly time, lowering costs, and avoiding anti-slip failure caused by rubber aging. This also reduces the use of adhesives or rubber materials, aligning with the automotive industry's trend towards lightweight and green manufacturing.

[0031] See attached document Figure 4-5The honeycomb core 44 is fixedly installed on the inclined inner wall of the first reinforcing tooth plate 41 and the second reinforcing tooth plate 42. The honeycomb core 44 shares the load through its in-plane compressive strength, thereby improving the overall bending stiffness of the beam body 1 to a certain extent. The serrations of the first reinforcing tooth plate 41 and the second reinforcing tooth plate 42 form a mechanical lock with the honeycomb core 44 to prevent interlayer peeling.

[0032] See attached document Figure 4 The positioning block 45 is fixedly installed on the flat inner wall of the second reinforcing tooth plate 42. The positioning block 45 connects and positions the crossbeam body 1 and the car seat, which can realize rapid positioning between them and improve the automated assembly efficiency between the car seat and the crossbeam assembly.

[0033] See attached document Figure 3-4 An extension seat 6 is fixedly connected to the bottom surface of the main body 1 of the crossbeam. The extension seat 6 increases the support area at the bottom of the main body 1 of the crossbeam, thereby increasing the contact area between the bottom of the main body 1 of the crossbeam and the inner wall of the car. This allows the loads transmitted from the crossbeam assembly to the inner wall of the car, such as gravity, impact force, and vibration load, to be distributed over a larger area, thereby reducing the stress per unit area and improving the reliability of the connection. A damping layer 43 is fixedly connected between the bottom surface of the extension seat 6 and the top surface of the first reinforcing tooth plate 41, and a damping layer 43 is fixedly connected between the bottom surface of the second reinforcing tooth plate 42 and the top surface of the main body 1 of the crossbeam. The damping layer 43 is mainly composed of viscoelastic damping material, such as butyl rubber. The damping layer 43 absorbs vibration energy through shear deformation, reduces fatigue damage to the main body 1 of the crossbeam under dynamic load, effectively extends its fatigue life, and at the same time suppresses structural noise and improves ride comfort.

[0034] See attached document Figure 1 and attached Figure 5 The side of the extension seat 6 is fixedly connected to a welding edge 2, and the bottom surface of the welding edge 2 is fixedly connected to a first reinforcing tooth plate 41. The welding edge 2 can be used to weld and fix the bottom end of the crossbeam assembly to the car.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
